any command line paramater changed the register allocation produced by
PBQP.
Turns out variety is not the spice of life.
Fixed some comparators, added others. All good now.

assert()s, switching to void-casts. Removed an unneeded Compiler.h include as
a result. There are two other uses in LLVM, but they're not due to assert()s,

* Enabled R1/R2 application for nodes with infinite spill costs in the Briggs heuristic (made
safe by the changes to the normalization proceedure).
* Removed a redundant header.

* Fixed a reduction bug which occasionally led to infinite-cost (invalid)
register allocation solutions despite the existence finite-cost solutions.
* Significantly reduced memory usage (>50% reduction).
* Simplified a lot of the solver code.
